베트남 이주여성과 그 자녀의 파찰음 음향학적 특징 = Acoustic characteristic of affricate spoken by Vietnamese migrant female and children

다국어 초록 (Multilingual Abstract)

Purpose

Analyze the characteristics of an acoustical sound of affricates in migrated Vietnamese women and their children to see what differs from Korean women and their children. This study is designed to provide basic data for multi-cultural family.

Subject and Method

This research was targeted for 17 immigrated Vietnamese women and their children, Korean women and their children. Praat(Version 5.4.12) were used to record voices. Duration of Affricates, /ca, cʰa, cʹa, aca, acʰa, acʹa/, were divided into explosion duration, duration of frication and duration of aspiration. Then after vowel pitch was measured.
T-test was conducted after solving average value and standard deviation using SPSS 20.0.

Results

Having analyzed explosion duration, duration of frication and duration of aspiration of affricates at initial word sound, it appeared to have all different results except for the result of duration of aspiration. Migrated Vietnamese women's frication duration were tested to have longer frication duration in a tense than in a lax.
Duration of frication of Korean children and migrated Vietnamese were shown from greatest to least order of a lax, an aspirate and a tense. As for duration of aspiration in those four groups, an aspirated had longer sound than a lax. And a tense showed in duration of aspiration for migrated Vietnamese women. In the medial word position, explosion duration of Korean women and migrated Vietnamese women were shown from greatest to least order of an aspirated, a tense and a lax equivalently appeared. And as for Vietnamese children, it was in the order of aspirated, lax and tense, lax and tense appeared equally in migrated Vietnamese women group.
Having analyzed after vowel pitches, after vowel pitches from initial sound position appeared to have in order of an aspirated, a tense and a lax in groups of Korean women and their children, migrated Vietnamese women and their children. As for Korean women, Vietnamese women and Korean children group showed in the order of an aspirated, a lax and a tense. As for Vietnamese children group, it appeared to have in order of an aspirate, a lax and a tense.
Having measured hold in a medial sound position, Korean women and their children, Vietnamese women their children showed order of a tense, an aspirated and a lax.



Conclusion

Having analyzed explosion duration, duration of frication and duration of aspiration of affricates in initial word sounds, all four groups resulted differently. Especially for migrated Vietnamese women, duration of aspiration appeared in a tense. Meanwhile, significant difference appeared in aspirated for duration of frication and duration of aspiration. And aspirated duration of aspiration, Korean children and Vietnamese children showed significant gap or differences in their duration of frication and duration of aspiration.
Comparing results between Korean women and migrated Vietnamese women in middle sound position, differences were caught in aspirated duration of frication and duration of aspiration. In a tense, meaningful differences were found in duration of aspiration. In addition, duration of aspiration were found in a lax and a tense. Having compared Vietnamese children and Korean children, it appeared to have meaningful differences in duration of frication. Tenses duration of frication appeared to have meaningful differences as well.
Having analyzed vowel pitches, it appeared to have meaningful differences in Korean women and Vietnamese women in its aspirated. Migrated Vietnamese women pitch value appeared to have inadequate compared to other groups. It didn't show meaningful differences for Koran children and Vietnamese children in initial and medial of word sounds.
Explosion duration in the middle word sound, in Korean women and in migrated Vietnamese women group, meaningful differences were found in a lax. In a group of Korean and migrated Vietnamese children, meaningful differences in a tense were found. Migrated Vietnamese women group appeared to have weak differences in a lax, an aspirated and a tense compared to other diagnosed groups.
